PowerShell ISE Hacking: Change default save encoding to ASCII

If you want to do this, you won’t really need much of an explanation as to why I’m posting this. As to the rest of you, never mind; stick with your BigEndian Unicode (hint: powershell console and other console applications prefer ASCII) :)

First up, create yourself a Windows ISE Profile script that will be loaded by default when ISE starts (and/or when you open a new “Tab”)

# run this one-liner from within ISE through the interactive window (command pane):
if (-not (test-path $profile)) { md -force (split-path $profile); "" > $profile; psedit $profile }

Now, put this one-liner (well, it could fit on one line) in your $profile:

# watch for changes to the Files collection of the current Tab
register-objectevent $psise.CurrentPowerShellTab.Files collectionchanged -action {
    # iterate ISEFile objects
    $event.sender | % {
         # set private field which holds default encoding to ASCII
         $_.gettype().getfield("encoding","nonpublic,instance").setvalue($_, [text.encoding]::ascii)
Every time the tabs "files" collection changes, it will set the default save encoding to ASCII for all files in that tab. As the profile is loaded in each tab, all files in all tabs will default to ASCII when saving. No more "save as" annoyances; just hit save and ASCII will be used for encoding. "Save as" will still let you save as unicode if you wish.

Have fun!
